One Day One GNU/Linux Command
=============================
fg -- Place a job in the ForeGround.
Summary:
Normally user can run many jobs in background, by adding & at end of
the command (ex: sleep 10 &).
fg is a shell command. It is used to move a job from background to the
foreground, as if it is NOT started with `&'. If JOB is not present,
then current/last job is used.
Examples:
$ sleep 100 & -- Start a dummy job in background.
$ fg -- Move the last job to foreground.
$ sleep 150 & -- Dummy job 1
$ sleep 140 & -- Dummy job 2
$ sleep 130 & -- Dummy job 3
$ jobs -- List all active jobs.
$ fg 2 -- Move the 2nd active job to foreground.
Read: help fg, jobs
